unable to paste from word with icon (1 post)

I have this issue with a couple of my blogs and am unable to figure out why it works on some and not on others.

When I hit the paste from Word icon, the screen comes up where I would be able to paste into but there is no flashing cursor and it won't allow the paste command. The paste text icon works fine but Word isn't working at all.

I've tried the tinymce-advanced bar and still the same issues with its paste from Word.

This happened in 2.5.1 and with current 2.6. I've cleared cache in browser. Deleted the files in wp-content/uploads/js_cache. And still nothing.
